• If you are trying to use Boolean operators, they must be ALL CAPS: (("_ baum, pagine la scienza") OR ((("_ raum, paging i sciences") OR ("_ raum, aging i sciences")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"_ baum, pagine la scienza\") or (((\"_ raum, paging i sciences\") OR (\"_ raum, aging i sciences\"))))".
• Removing quotes may allow a broader search: (( _ baum, pagine la scienza ) or ((( _ raum, paging i sciences ) OR ( _ raum, aging i sciences )))).
• Adding a wildcard symbol may retrieve word variants: (("_ baum, pagine la scienza") or ((("_ raum, paging i sciences") OR ("_ raum, aging i sciences"))))*.
